Document Summary

4. 1 moment of a force scalar formation. When a force is applied to a body, it will produce a tendency for the body to rotate about a point that is not the line of action of the force. Tendency to rotate: torque, most often called the moment of a force. Magnitude of the moment is directly proportional to the magnitude of f and the perpendicular distance or moment arm d. larger force/longer moment arm = greater moment/turning effect. The moment mo perpendicular to the plane, is a vector quantity since it has a specified magnitude and direction. about point o, or about an axis passing through o and. The magnitude of mo is mo = fd d: moment arm or perpendicular distance from the axis at point o to the line of action of the force. Units of moment magnitude consist of force times distance (e. g. n*m)
